Just saw this on yesasia - I have been wanting to watch this for a while now. Looks to come out on Dec. 27th.

The King and The Clown director Lee Joon Ik returns to the Joseon era with the riveting period actioner Blades of Blood. Based on a comic by Park Heung Yong, the film matches up two of Korea's most acclaimed and charismatic actors, Cha Seung Won (Secret) and Hwang Jung Min (A Man Who Was Superman), in a duel to the death. The two stars act up a storm as swordsmen who once shared the same dream, but war, politics, and power drive them down opposite paths of blood and betrayal. One of the most anticipated Korean films of 2010, Blades of Blood also co-stars Baek Sung Hyun (Our School ET) and Han Ji Hye (My Boyfriend Is Type-B).
In the late 16th century, the Joseon kingdom is thrown into chaos by the threat of a Japanese invasion. Royal descendant Lee Mong Hwak (Cha Seung Won) and legendary blind swordsman Hwang Jung Hak (Hwang Jung Min) were once allies who dreamed of stamping out social inequality and corruption, and creating a better world. Persecuted by the court, Lee forms a rebel army in hopes of overthrowing the inept king and taking the throne himself. Lee is willing to kill recklessly and betray former comrades to forge his bloody path to the palace, but Hwang Jung Hak stands in the way.
